REFRIGERTOR SHIPPING-@ASE SPECIFICATION forming part of Letters PatentNo. 608,701, dated August 9, 1898. Application filed October l, 1896.Renewed April, 1898. Serial No. 676,593. (No model.)

To all whom t may con/06771,:

being had to the accompanyingr drawings, and

to letters of reference marked thereon, which form a part of thisspecification.

This invention relates to improvements in refrigerator shipping-cases,and has for its object to provide acase for transporting perishablearticles in which the parts are so constructed and arranged as to givethe best results with ecomomy of space and simplicity and cheapness ofconstruction, the device comprising an inclosing case or receptaclehaving openings in the top and bottom, within which case or receptacleis located an inner receptacle presenting two compartments with aremovable ice-box interposed between them and forming the inner sidewalls thereof, said ice-box having a spring-supported false bottom, aspace for the circulation of air entirely surrounding the innerreceptacle, and openings which register with the openings in theinclosing case to secure a proper circulation conduced by a peculiararrangement and organization of the several parts; and with this end inview the invention consists in the special construction and combinationof the parts, as will be hereinafter fully set forth, and pointed out inthe claims.

In the accompanying drawings, forming part of this speciiication, Figurel is a vertical longitudinal sectional view through a refrigeratorshipping-case constructed in accordance with my invention, and Fig. 2 isa transverse sectional view on the line 2 2 of Fig. l.

Referring to the drawings, A designates the inclosing case orreceptacle,which is provided with a cover A', handhelds a at its ends,and feet a', which support the devicea suitable distance above the door.Within the inclosing case .A is located an inner receptacle B, which isprovided on its four sides with projections or pins Z), covered byrubber tips D', said tips bearing against the inner sides of the case Ato position the receptacle centrally therein. By this arrangementa'space a2 for the circulation of air is provided which entirelysurrounds the inner receptacle B.

To the inner side of the side pieces of the receptacle B are securedvertical angle-stri ps d, presenting iianges or guide-rails which engagethe ends of an ice-box O, said ice-box dividing the receptacle B intotwo compartments D D, which communicate with each other by way of aspace left below the icebox by supporting the same upon feet c, formedby projections and rubber tips similar to those hereinbefore mentioned.W'ithin the ice-box O is a plate or false bottom C', supported uponhelical springs c'. The ice is `placed upon the plate or false bottom C,

and as the ice melts it will be raised by the tension of the springsabove the water or drippings which collect in the bottom of the ice-box.This provides for keeping the ice out of contact with the water, as theplate or false bottom moves upward automatically as the weight of theice is reduced by melting.

A cover E is provided which fits over the top of the inner receptacle Bto close the compartments D and ice-box C, said cover being providedwith a central opening e, through which the air may pass from theice-receptacle into the'air-space a2 when the temperature is lowertherein than in the ice-chamber, and when the temperature outside islower than in the shipping-case cold air will pass through 'the openingse4 and e into the icechamber. l/Vhen the conditions are reversed, theair will pass out of the openings e into the upper air-space a2 and willdescend, passing out of the opening e3. Generally speaking, thecirculation will be through the opening e2 into the compartments Dupwardly and out of the openings e', the warm air rising and passing ontof the opening e4, While the cold air descends and is then carriedupwardly by the inflow of air through the opening e3. Thus a constantsupply of fresh air takes the place of that which passes out of theopening e4. This circulation is necessary when shipping articles thatwould otherwise foul the air if confined in the compartments; but inshipping bottled goods such circula- IOO tion would not be required. Theopenings e3 and e4 may be provided with Stoppers of ordinaryconstruction for closing them when desired.

The construction herein shown and described provides a very simple,cheap, and effective refrigerator shipping-case in which perishablearticles may be transported Without fear of spoiling, and by properattention the air within the case can be maintained at a uniformtemperature, which is very necessary in transporting certain classes ofarticles. It Will be noted that the ice-box O forms a side of eachcompartment D, and thereby offers the best results in cooling the airWithin said compartments.

If desired, the device can be placed within a wooden box to betterretain the cold air, and, in fact, the inclosing case could be made ofwood instead of metal.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

l. In a refrigerator shipping-case, the combination of the inclosingcase A, having a cover with a central opening e4, an inner receptaclel5, having openings e near its upper end, and a cover with an openinge", projections or pins covered by rubber tips carried by the receptacleand cover which bear against the case to provide spaces a2 by locatingthe receptacle centrally therein, vertical strips or guides d secured tothe inner side of the side pieces of the receptacle I3, a removableice-box C, placed Within the receptacle B, to bear at its ends againstthe guides or strips cl and provide two compartments D, D; together withhelical springs resting upon the bottom of the ice-box C, and a plate orfalse bottom C mounted on said springs, the bot tom of the inclosingcase having a central opening e3 said opening and the opening e4 beingnormally closed by Stoppers, substantially as shown.

2. In arefrigeratorshipping-case, the coinbination 0f an outer casingwith legs or supports, the same having in the top and bottom openings,of an inner receptacle with projections to hold the same away from theinner walls of the outer case, said inner receptacle having verticalstrips, central openings in the top and bottom of said receptacle, sodisposed as to be on a line with the openings in the top and bottom ofthe outer casing, and openings near the upper edges of the side walls,together With a central ice-receptacle which engages with the verticalstrips, the bottom of the ice-receptacle having legs or projections toengage the bottom of the inner receptacle, and a spring-supportedtraycarried by the ice-receptacle substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.
